Abstract:

A Swing-arm Integrated Exhaust Silencer is disclosed. The Silencer is designed to be incorporated within the conventional swingarm of a motorcycle. One version has a removable silencer cartridge that installs within the inner chamber of the motorcycle's swingarm. Another version allows the exhaust stream to be diverted from the conventional silencer and into the inner chamber of the swingarm. In either version, the swingarm has plurality of apertures formed in it to allow for exhaust gas exit. The invention includes an adapter device that splits the exhaust gas exiting the engine and redirects it into the swingarm-integrated silencer. The exhaust adapter device is somewhat flexible to allow for movement between the swingarm, the engine, and the conventional silencer's exhaust pipe.
